Arthroscopic surgery method for ankle ligament reconstruction

Abstract

An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

The invention claimed is: 
     
       1. An arthroscopic surgery method for ankle ligament reconstruction comprising:
 a probe that defines a longitudinal axis and transmits ultrasonic vibration; and 
 a treating portion provided on a distal portion of the probe, the treating portion including a distal surface that intersects with the longitudinal axis, a first projection that projects from the distal surface along the longitudinal axis, and a plurality of second projections that project from the distal surface along the longitudinal axis and have a shorter projecting length than the first projection, 
 the method comprising:
 forming a guide hole in each of a fibula, a talus, and a calcaneus; 
 inserting the first projection into the formed guide hole; 
 moving the first projection along the guide hole so that a bone hole that is larger than the guide hole is formed in each of the fibula, the talus, and the calcaneus by the second projections that outputs the ultrasonic vibration; and 
 fixing a tendon to the formed bone hole. 
 
 
     
     
       2. The method according to  claim 1 , wherein:
 the treating portion of the ultrasonic treatment device further comprises a plurality of third projections or an edge on a side surface, and 
 the method further comprises removing a persistence ligament by the third projections or the edge before forming the guide hole. 
 
     
     
       3. The method according to  claim 1 , wherein the first projection is disposed in a center of the distal surface. 
     
     
       4. The method according to  claim 1 , wherein the bone hole is elliptic. 
     
     
       5. The method according to  claim 1 , wherein the bone hole is round. 
     
     
       6. The method according to  claim 1 , wherein the guide hole is formed by a treatment device being an ultrasonic treatment tool. 
     
     
       7. The method according to  claim 1 , wherein the guide hole is formed by a treatment device being a surgical instrument. 
     
     
       8. A method of forming a hole for fixing a tendon to a bone comprising:
 a probe that defines a longitudinal axis and transmits ultrasonic vibration; and 
 a treating portion provided on a distal portion of the probe, the treating portion including a distal surface that intersects with the longitudinal axis, a first projection that projects from the distal surface along the longitudinal axis, and a plurality of second projections that project from the distal surface along the longitudinal axis and have a shorter projecting length than the first projection, 
 the method comprising:
 forming a guide hole in the bone; 
 inserting the first projection into the formed guide hole; and 
 moving the first projection along the guide hole so that a bone hole that is larger than the guide hole is formed by the second projections outputting the ultrasonic vibration. 
 
 
     
     
       9. The method according to  claim 8 , wherein the guide hole is formed by a treatment device being an ultrasonic treatment tool. 
     
     
       10. The method according to  claim 8 , wherein the guide hole is formed by a treatment device being a surgical instrument.
